Abstract
Es wird ein Verfahren (500) zur Steuerung eines Drehmoments eines Elektromotors eines elektrohydraulischen Systems vorgeschlagen. Das Verfahren (500) weist einen Schritt des Auswählens (510) eines Werts eines Vorgabedrehmoments in Abhängigkeit von einem aktuellen Druck in einem Hydraulikkreis des elektrohydraulischen Systems auf. Das Verfahren (500) weist auch einen Schritt des Bestimmens (520) eines Ansteuersignals zur Steuerung des Drehmoments des Elektromotors basierend auf einem Solldrehmoment und dem Vorgabedrehmoment auf.
